Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides a Figures 1-3 wheelchair racing helmet as shown, including a helmet main body 1. A plurality of connecting pieces 2 are arranged below the helmet main body 1. The connecting pieces 2 are beneficial to support the buckle strap 3 and facilitate the installation of the buckle strap 3. The bottom end of the connecting piece 2 is provided with the buckle strap 3.

[0025] Furthermore, a fixing mechanism 4 for connecting and fixing the buckle strap 3 is arranged on the connecting piece 2. The fixing mechanism 4 includes a plug-in board 41. The plug-in board 41 is beneficial to connect the buckle strap 3 with the connecting piece 2, facilitate the positioning and installation of the buckle strap 3, and at the same time is beneficial to connect and support the buckle strap 3. The plug-in board 41 is used for the plug-in positioning of the buckle strap 3 and the connecting piece 2. The plug-in block 42 is beneficial to limit the relative position of the connecting piece 2 and the plug-in board 41, and further is beneficial to the installation and disassembly of the buckle strap 3. It is convenient to disassemble and replace the buckle strap 3 after wear, and the operation is convenient. The plug-in block 42 is used for the connection limit of the plug-in board 41. The plug-in block 42 is slidably arranged on the side of the plug-in board 41. The connecting rod 43 is beneficial to pull the plug-in block 42 for operation, facilitate the traction of the plug-in block 42, and connect or disconnect the plug-in block 42 with the plug-in board 41. The connecting rod 43 is used to drive the movement of the plug-in block 42. When it is necessary to disassemble the buckle strap 3, first pull the connecting plate 44 to move, so that the connecting plate 44 drives the connecting rod 43 to move. The connecting rod 43 pulls the plug-in block 42 to move, so that the plug-in block 42 is disengaged from the connecting piece 2. At this time, the position limit of the plug-in board 41 is released. Then pull the buckle strap 3 to make the buckle strap 3 drive the plug-in board 41 to be disengaged from the connecting piece 2, and the buckle strap 3 can be disassembled.

[0026] Furthermore, the bottom end of the plug-in board 41 is fixedly connected to the buckle strap 3. An installation groove is opened at the bottom end of the connecting piece 2. The plug-in board 41 is slidably inserted into the inner cavity of the installation groove. A limit groove matching with the plug-in block 42 is opened on the side of the plug-in board 41.

[0027] Further, a connection frame 45 is fixedly connected to the side of the connecting member 2.

A first sliding groove is provided on the side of the connecting member 2, and the insertion block 42 is slidably inserted into the inner cavity of the first sliding groove. One end of the connecting rod 43 is fixedly connected to the insertion block 42. A bearing plate 46 for slidably supporting the connecting rod 43 is arranged on the side of the connection frame 45. The bearing plate 46 is conducive to the sliding of the connecting rod 43 on it, facilitating the sliding support of the connecting rod 43. At the same time, it is conducive to limiting the movement position of the connecting plate 44 and facilitating the limitation of the movement position of the insertion block 42. A plurality of mounting bolts 5 are threadedly inserted through the side of the bearing plate 46. The mounting bolts 5 are conducive to the installation and disassembly of the connecting plate 44, facilitating the installation and disassembly of the connecting rod 43 and the insertion block 42. One end of the mounting bolt 5 is threadedly inserted through the connection frame 45, and the outer wall of the connecting rod 43 is slidably inserted through the bearing plate 46.

[0028] Further, the other end of the connecting rod 43 is fixedly connected to a connecting plate 44 for driving its movement. The connecting plate 44 is conducive to pulling the connecting rod 43, facilitating the traction of the connecting rod 43. At the same time, it is conducive to limiting the movement positions of the connecting rod 43 and the insertion block 42. A plurality of fixing frames 47 are fixedly connected to the side of the bearing plate 46. The fixing frames 47 are L-shaped. The fixing frames 47 are conducive to the installation of the elastic ropes 48, facilitating the traction of the elastic ropes 48. A plurality of elastic ropes 48 for driving the movement of the connecting plate 44 are arranged inside the connection frame 45. The pulling force of the elastic ropes 48 is conducive to pulling the connecting plate 44 to move, facilitating the restoration of the connecting plate 44 and the connecting rod 43 to their original positions after movement, and facilitating the repeated operation of the insertion block 42. One end of the elastic rope 48 is fixedly connected to a positioning column 482. The positioning column 482 is conducive to the installation of the elastic rope 48, facilitating the support of the elastic rope 48. The outer wall of the positioning column 482 is threadedly inserted through the connecting plate 44. The other end of the elastic rope 48 is fixedly connected to a mounting column 481. The mounting column 481 is conducive to the installation and disassembly of the elastic rope 48, facilitating the operation of the elastic rope 48. The outer wall of the mounting column 481 is threadedly inserted through the inner wall of the fixing frame 47.
